Children with viral-induced wheeze often receive oral or inhaled corticosteroids or a leukotriene inhibitor despite a lack of good evidence that they work. Three studies shed light on this condition.
In a double-blind, randomized trial, 220 children (age range, 1–5 years) who had histories of intermittent wheeze associated with respiratory tract infection (RTI) received albuterol plus a 7-day course of inhaled budesonide (1000 µg twice daily), montelukast (4000 µg daily), or placebo at the onset of each RTI.
